3. No, the moths did not change color over this time period. The change in population was due to the increased presence of soot in the environment, which caused the black moths to be better camouflaged and therefore more successful in surviving.
4. The black moths were the majority of the population during this time period because they had a natural advantage in the environment created by the Industrial Revolution. The soot and pollution created by the factories provided camouflage for the black moths, making them less visible to predators.
5. Without the shrubs and lower leaves on the trees, the long-neck giraffes would have an advantage over the short-neck giraffes. The long-neck giraffes would be able to reach the higher leaves on the trees, while the short-neck giraffes would not. Over time, the population of long-neck giraffes would increase, while the population of short-neck giraffes would decrease.
6. No, the short neck giraffe is a distinct species of giraffe with a naturally shorter neck than other species of giraffe. It is not possible for the short neck giraffe to grow a longer neck.
